Merge tag 'io_uring-5.19-2022-06-16' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:
 "Bigger than usual at this time, both because we missed -rc2, but also
  because of some reverts that we chose to do. In detail:

   - Adjust mapped buffer API while we still can (Dylan)

   - Mapped buffer fixes (Dylan, Hao, Pavel, me)

   - Fix for uring_cmd wrong API usage for task_work (Dylan)

   - Fix for bug introduced in fixed file closing (Hao)

   - Fix race in buffer/file resource handling (Pavel)

   - Revert the NOP support for CQE32 and buffer selection that was
     brought up during the merge window (Pavel)

   - Remove IORING_CLOSE_FD_AND_FILE_SLOT introduced in this merge
     window. The API needs further refining, so just yank it for now and
     we'll revisit for a later kernel.

   - Series cleaning up the CQE32 support added in this merge window,
     making it more integrated rather than sitting on the side (Pavel)"
